Rovio is celebrating 100 million downloads of the (quite apparently) popular Bad Piggies with a new update.

Bad Piggies is the Angry Birds spinoff that lets you play as the pigs as they build vehicles from scrap and try to navigate their way through levels without being blown up. It's getting a new Sandbox level called Little Pig Adventure and a new part called the gearbox, which allows you to make your inventions travel in reverse.

There are also some new achievements to collect, so download Bad Piggies for $0.99 and start building.

The Firm is an arcade-style video game where you are a small paper-pushing cog in the big machine of a corporation, and Sunnyside has released a new update that adds a ton of new stuff.

Now the game has all new music and sounds, a ranking system, new cards and game mechanics, social functions, and new options like a colorblind mode and "happy" ending (i.e. less... final). Sunnyside has also done away with the old in-app purchases so you can enjoy the game in full.

Kumobius has released a new purchasable chapter for their minimalist game, Duet, called the Encore Chapters. And once again you'll need to keep your two vessels in sync to survive the barrage of obstacles in your path.

The update includes a new story, music, and 30 new stages. It also includes new features such as two directional attack waves and boomerang blocks. Yikes.

You can download Duet for $2.99 and check out the new in-game update for $0.99.

Out there in the world, there are many people who are nervous while flying. Usually this nervousness isn't due to the technical wonder that is a massive tube of metal with wings managing to stay up in the air, but rather the chance that said tube doesn't reach its final destination. In order to help people understand the slim chances of the second scenario, Vanilla Pixel has released Am I Going Down?.

The app uses publicly available statistics to calculate the odds of any flight crashing, with a vast majority of odds coming out reassuringly high, and is meant to assure people that air travel is statistically very safe. Well, as long as you don't intend to catch the New York JFK to London Heathrow trip on a British Airways Boeing 747-400 every day for the next 25,433 years, in which case one of those flights may end a bit roughly for you.
